Lupinus antoninus is known only from the type locality on the southwestern slope of Anthony Peak in Mendocino County. The habit and pubescence resemble those of L. adsurgens, but the larger white flowers, the large seeds, and thick stems differentiate it morphologically. According to M. Conrad (1980), it also has different alkaloids. This taxon has not been seen since 1995 and may be extirpated. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
